Intel-Based Smb Servers Running Web, Email, and Database Applications PERFORMANCE OF FOUR INTEL-BASED SMB SERVERS RUNNING WEB, EMAIL, AND DATABASE APPLICATIONS *Greatest performance improvement was in comparison to the Intel Core 2 Duo processor E6400-based server. OUR FINDINGS OUR PROCESS The latest Intel® Xeon® processor E3-1240-based We measured the performance and performance small-to-medium business (SMB) server delivers per watt of four different Intel processor-based significantly better performance and performance SMB servers running simultaneous workloads that per watt than previous-generation Intel processor- exercised three of the functions a typical small based SMB servers while running typical office business server may have to handle: Web, email, applications. In our tests, the Intel Xeon processor and database services. Our tests reflect the E3-1240-based server delivered up to 495 percent priorities of SMB owners: increased efficiency and better performance than three previous- increased cost savings. Better workload generation Intel processor-based servers did. This performance results in more accomplished in less superior performance, for comparatively little time, and better performance per watt results in increase in cost, makes the new Intel Xeon lower power bills. We wanted to see if the new processor E3-1240-based server a wise choice for Intel Xeon processor E3-1240-based SMB server any small business seeking an all-in-one SMB could deliver both. server. JANUARY 2011 A PRINCIPLED TECHNOLOGIES TEST REPORT Commissioned by Intel Corp. PROJECT OVERVIEW Hardware ages out. As workloads become more demanding, older servers, and older desktop systems acting as servers, are increasingly unable to run them efficiently. SMB owners find their servers becoming bottlenecks to productivity, and even liabilities as they start to break down. Nonetheless, small businesses that are outgrowing their servers still question the performance benefits of newer servers. Can they continue to use their older desktop systems as servers? Were they to invest in a new server, how substantial would the performance gains in Web, email, and database applications be; how substantial would the power savings be; and what would the price differences be? In our tests, we address these questions by comparing a new Intel Xeon processor E3-1240-based server with that of several older Intel processor-based servers. The Intel Core 2 Quad processor Q8400-based server and Intel Core 2 Duo processor E6400-based server are intended to represent desktop systems acting as servers. We tested four one-socket servers with the following processors: • Intel Xeon processor E3-1240-based server (3.30 GHz, 8MB L3 cache) • Intel Xeon processor X3450-based server (2.66 GHz, 8MB L3 cache) • Intel Core 2 Quad processor Q8400-based server (2.66 GHz, 4MB L2 cache) • Intel Core 2 Duo processor E6400-based server (2.13 GHz, 2MB L2 cache) We used WebBench to simulate Web traffic, Average normalized performance 7.00 Microsoft® Exchange Load Intel Xeon processor E3-1240-based server Generator (LoadGen) to 6.00 simulate email activity, and 5.00 Intel Xeon processor X3450-based server DVD Store Version 2 (DS2) to 4.00 Intel Core 2 Quad 3.00 simulate database activity.

Higher numbers are better. Enterprise Edition. Performance of four Intel-based SMB servers running Web, A Principled Technologies test report 2 email, and database applications WHAT WE FOUND Figure 1 presents averaged results for the four Intel processor-based servers running the three workloads relative to the lowest-performing server, the Intel Core 2 Duo processor E6400-based server. While running the three benchmarks, the Intel Xeon processor E3-1240-based server delivered the following performance increases: 33.8 percent better than the Intel Xeon processor X3450-based server, 203.3 percent better than the Intel Core 2 Quad processor Q8400-based server, and 494.9 percent better than the Intel Core 2 Duo processor E6400-based server. For each benchmark, we assigned a value of 100 percent to that server’s results and then calculated the percentage performance improvement. This approach makes each data point a comparative number, with higher numbers indicating better performance. Finally, we took the percentage performance improvement over the Intel Core 2 Duo processor E6400-based server for the three benchmarks and averaged them. We also measured power consumption during the workload run. We took the averaged relative performance results and divided them by the active power consumption. We normalized those results to those of the Intel Core 2 Duo processor E6400-based server. As Figure 2 illustrates, the Intel Xeon processor E3-1240-based server produced the following performance-per-watt increase: 61.1 percent better than the Intel Xeon processor X3450-based server, 215.7 percent better than the Intel Core 2 Quad processor Q8400-based server, and 550.3 percent better than the Intel Core 2 Duo processor E6400-based server. Normalized performance/watt 7.00 As of February 15, Intel Xeon processor 6.00 E3-1240-based 2011, the prices for each Intel- server 5.00 Intel Xeon processor processor based server are as X3450-based server 4.00 follows: 3.00 Intel Core 2 Quad • Intel Xeon processor processor Q8400- E3-1240-based server: 2.00 based server $1,383.60 Intel Core 2 Duo Normalized performance/watt 1.00 processor E6400- • Intel Xeon processor based server X3450-based server: 0.00 Servers $1,344.09 • Intel Core 2 Quad Figure 2: Normalized performance-per-watt results of the Intel processor-based servers processor Q8400-based across the three benchmarks relative to the Intel Core 2 Duo processor E6400-based server: $985.26 server. Higher numbers are better. Performance of four Intel-based SMB servers running Web, A Principled Technologies test report 3 email, and database applications • Intel Core 2 Duo processor E6400-based server: $926.86 Figure 3 presents a comparison of price and performance increase of the Intel Xeon processor E3-1240- based server relative to the other Intel processor-based servers. The Intel Xeon processor E3-1240-based server’s 33.8 percent performance increase over the Intel Xeon processor X3450-based represents a substantial performance increase for a small increase in price. We present more detailed price listings in Appendix B. Price Performance Comparison increase increase Intel Xeon processor E3-1240-based server vs. Xeon processor X3450- $39.51 33.8% based server Intel Xeon processor E3-1240-based server vs. Core 2 Quad processor $398.34 203.3% Q8400-based server Intel Xeon processor E3-1240-based server vs. Core 2 Duo processor $456.74 494.9% E6400-based server Figure 3: Price and performance increase for the Intel Xeon processor E3-1240-based server relative to the other Intel processor- based servers. WHAT WE TESTED We ran the following three workloads simultaneously, as a typical small business server might. WebBench WebBench 5.0 (128-bit US version) is an industry-standard benchmark for Web server software and hardware. It uses PC clients to send Web requests to a server under test. It generates performance results by incrementally increasing the number of clients making HTTP 1.0 GET requests to the Web server; the result is a curve showing the server’s performance under increasing load. The peak of that curve represents the peak throughput of the server. WebBench reports both the total number of requests per second the server handled and the server’s total throughput in bytes per second. We ran the WebBench default ecommerce CGI test suite, which generates both secure and non-secure static and dynamic HTTP 1.0 GET requests. While running the ecommerce suite, the clients must negotiate to a secure Web server port using the Secure Socket Layer (SSL) protocol. A default WebBench test suite incrementally increases the number of clients making the HTTP 1.0 GET requests to the Web server. As the workload increases the number of clients, the Web server’s processor utilization also increases, until the clients saturate the processor in the Web server with work. Each workload point with a fixed number of clients is a WebBench “mix.” The ecommerce CGI test suite begins with a mix that involves one client; the next mix involves four clients; and each subsequent mix increases the number of clients by four. We modified the test Performance of four Intel-based SMB servers running Web, A Principled Technologies test report 4 email, and database applications suite so it would run the same number of clients, with 10 engines per client for the entire test. This allowed us to keep a constant Web load on the server. We used 45 clients on the Intel Xeon processor E3-1240-based server and the Intel Xeon processor X3450-based server, and scaled back to 30 clients on the Intel Core 2 Quad processor Q8400-based server and the Intel Core 2 Duo processor E6400-based server because these processors were unable to manage the greater workload. We performed only nine mixes for testing to limit the amount of time WebBench ran. To avoid any bottlenecks in the network cards, we used a ratio of 15 WebBench clients per NIC and added network adapters to the server hardware configuration as needed. We ran this workload on the four servers for 45 minutes each. DVD Store DVD Store Version 2 is an open-source application with a back-end database component, a front-end Web application layer, and a driver layer that operates as the middle tier and actually executes the workload.

  • A Dual Core Processor Has Two Cores (Essentially, Two Cpus on One Chip)
    Faculty of Engineering & Information Technology Al-Azhar University-Gaza Dr. Mohammad Aqel Microprocessors and Interfacing (ITCC 3301) Homework (1) Intel Core is a brand name used for various mid-range to high-end consumer and business microprocessors made by Intel. In general, processors sold as Core are more powerful variants of the same processors marketed as entry-level Celeron and Pentium. Similarly, identical or more capable versions of Core processors are also sold as Xeon processors for the server market. The current lineup of Core processors includes the latest Intel Core i7, Intel Core i5 and Intel Core i3, and the older Intel Core 2 Solo, Intel Core 2 Duo, Intel Core 2 Quad, and Intel Core 2 Extreme lines. 1- The original Core brand refers to Intel's 32-bit dual-core x86 CPUs. 2- Unlike the Intel Core, Intel Core 2 is a 64-bit processor, supporting Intel 64. The Core brand comprised two branches: the Duo (dual-core) and Solo (Duo with one disabled core). A dual core processor has two cores (essentially, two CPUs on one die (piece) silicon chip (IC)). Core2Duo is a specific dual-core processor design. Thus, all Core2Duo CPUs are dual-core CPUs, but not all Intel dual-core CPUs are Core2Duo designs. Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module.

Petr Olivka [email protected] Department of Computer Science FEI VSB-TUO CISC Processor - Intel x86 This chapter will introduce the CISC processors evolution. We will try to illustrate the history on one typical processor, because the comparison of multiple processors simultaneously would not be clear for readers. But the selection of one typical processor is complicated due to a variety of products and manufactures in the past 30 years. We have decided to describe in this presentation one of the best- known and longest mass-produced processors in existence. We definitely do not want to say that it is the best technology or that these are processors with the highest performance! The Intel x86 processors are the selected product line. Intel 8080 (Year-Technology-Transistors-Frequency-Data bus-Address Bus) Y: 1974 T: NMOS 6μm Tr: 6000 F: 2MHz D: 8b A: 16b This 8 bit processor is not directly the first member of x86 series, but it can not be skipped. It is one of the first commercially successful microprocessors. This microprocessor became the basis for a number of the first single-board computers and its instruction set inspired other manufacturers to develop 8-bit processors.
